I had a look at the burned in question at Alex's place and he showed me a barrel of powdery ash and also some char he can produce at will. He has a 500 ton stash - or did before winter - of bashed up wood fuel. Basically shards and splinters from a giant hammermill. 

Pretty interesting. However the really interesting device was the very small burner that used the same crappy fuel to heat water in a pond. It is a condensing heat exchanger and has spectacularly low CO. 

I am glad to hear the BLDD is getting some attention again. There is a new BLDD stove for cooking and space heating coming out of the University of Johannesburg and week now.
